| Metal-insulator-metal diodes work by using two different metals with different work functions, allowing electrons to tunnel across the gap very quickly without consuming excess power or generating excess heat. |
Researchers at Oregon State University (OSU)claim to have perfected a better method for "quantum tunneling" using metal-insulator-metal (MIM) architecture, potentially paving the way for faster, lower power and cooler running electronics. Quantum tunneling offers advantages over traditional current flow, in which electrons jump across device barriers rather than traversing through them, slowing down the flow, increasing power requirements and generating excess heat. Traditional tunneling diodes use a heavily doped p–n junction which has limited their use to discrete devices.
